What are different ways to insert a document(record) into MongoDB using Mongoose?
My current attempt:
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var notificationsSchema = mongoose.Schema({
"datetime" : {
type: Date,
default: Date.now
},
"ownerId":{
type:String
},
"customerId" : {
type:String
},
"title" : {
type:String
},
"message" : {
type:String
}
});
var notifications = module.exports = mongoose.model('notifications', notificationsSchema);
module.exports.saveNotification = function(notificationObj, callback){
//notifications.insert(notificationObj); won't work
//notifications.save(notificationObj); won't work
notifications.create(notificationObj); //work but created duplicated document
}
Any idea why insert and save doesn't work in my case? I tried create, it inserted 2 document instead of 1. That's strange.
The .save()
is an instance method of the model, while the .create()
is called directly from the Model
as a method call, being static in nature, and takes the object as a first parameter.
var mongoose = require('mongoose');
var notificationSchema = mongoose.Schema({
"datetime" : {
type: Date,
default: Date.now
},
"ownerId":{
type:String
},
"customerId" : {
type:String
},
"title" : {
type:String
},
"message" : {
type:String
}
});
var Notification = mongoose.model('Notification', notificationsSchema);
function saveNotification1(data) {
var notification = new Notification(data);
notification.save(function (err) {
if (err) return handleError(err);
// saved!
})
}
function saveNotification2(data) {
Notification.create(data, function (err, small) {
if (err) return handleError(err);
// saved!
})
}
Export whatever functions you would want outside.
More at the Mongoose Docs, or consider reading the reference of the Model
prototype in Mongoose.
